Master's enrollment mathematics exams have been very difficult than those of candidates, many candidates have lost their overseas opportunities due to math. Especially for the Candidates of the University of Arts and Sciences or Economic Academics, the difficulty of this class can be called the biggest in all subjects and is most worrying. Since the 1997 Mathematics Examinal Outline, the candidates generally reflect the problem that the questions are increasingly difficult. Mathematics has almost become a "gateway" that is difficult to pass over some candidates. In this case, some candidates "the disease is in a hurry", which blindly participates in various counseling classes. As a result, there is a lot of time energy, but the effect is not good. From 1987 to 2001, the math admissions lines in this fifteen years are almost the lowest in the three basic courses (mathematics, English, political) of the exam. Why does this happen? Some experts: First, the amount of postgraduate mathematics test questions and difficulty in the current college entrance examination is large, many candidates reflect even in college age mathematics, but if they don't care seriously, they are not good to review. It is also difficult to achieve good results, even can't even go. Second, the present graduate mathematics test paper relatively other courses, the knowledge is more, the knowledge is width, strong comprehensive, and high skill. If you only master knowledge, you don't have a solution method and skill. It is difficult to test. Compared with the 2002 mathematical examination outline, the mathematics has also changed in 2003, and the mathematics of the entrance examination will be classified into the professional one, two, three, four, and the enrollment units are beneficial. Selection of the principles of talent and adaptation training requirements. This means that the direction of mathematics examination will be more focused on the comprehensive application of the candidates on the basis of grasp. How to review the mathematics, it can be said that it is the key to the examination of science and engineering and economic candidates. Retrieved, you can pull others very far away; if you review it, you will suffer, and even lose the opportunity. The mathematical content of the postgraduate includes three parts: calculus, linear algebra, probability theory and mathematical statistics; also divided into four categories, namely one, number two, three and numbers, different professional requirements for different professional requirements Category, although these four categories have different difficulties and side focus, as the mathematic discipline is characterized, review methods are also substantially the same, and mathematics relatively English, as long as the method is proper, it is very fast. So just master the correct review method, you can do half a level. The following preparation experience may give candidates to inspire. Mathematical preparation must have a review schedule, which is to have a careful plan. According to the plan, step by step, avoid assault, temporarily holding Buddha feet. Mathematics is a basic discipline, its improvement ability is a long-term accumulated process, so the review time should be appropriate, step by step. Based on the experience of the previous year, many candidates roughly in March, and the candidates that have poor mathematical bases can be appropriately advanced. Review must have a viable plan to ensure the progress and effect of review. Generally, the review can be divided into four phases, and the start time of each phase and the task candidates to be completed should be clearly defined to ensure the feasibility of the plan. According to the experience of the candidates in the years, it can be divided into the following stages: the first stage is the basis for the examination of the basic knowledge of the examination, under the basis of the examination outline, under the basis of the basic knowledge of the exam, understand the study mathematics Basic content, focus, difficulties and features. This time period is generally defined as June. The second phase is based on the first phase, do a certain number of questions, focus on solving the problem of solving the problem. Generally from July to October.

At this stage, you should pay attention to summarize, you know what angle after getting the question, you can solve a few steps, each question is not required to write a complete step, as long as the idea is, the procedure will be done, candidates It can be flexible as appropriate, so that you can save time to see more questions. The selected test can be the problem of calendar year, or it can be an exercise question in the book, but the topic must do it, and must be done in strict accordance with the requirements of the implementation test, grasp the characteristics of the true subject and the disclant ideas and arithmetic steps. The third stage is a practical training stage, from the middle of November to December, this is also a very important stage before the exam. Candidates should make the final card, mature formula, and systematically do a few sets of simulation test papers, and self-test results. Before doing analog questions, you must systematically memorize the basic formula. Do you have to pay attention to the quality, both speed, and strict steps, format and calculation accuracy. The final stage is the pre-test sprint, from late December to the exam. In response to the problem of problems that occur during the simulation test, check the prostitutes to take the test in the best state. Candidates should understand that learning mathematics is a long-term process, causing a half-point speculation, so the test of the pre-test, the practice of temporary Buddha is not enough, only according to his own plan, going to prepare for it, can not change It should be changed, as long as its comprehensive capacity is improved, no matter how changes in the exam, you can achieve good results. Eat the test outline requirements to accurately review the positioning. The postgraduate project is the fundamental basis for the propositions of the Ministry of Education, guiding propositions and candidates. It strictly delineates the scope and difficulty requirements of various professional candidates, which is also the basis for the formulation of candidates. First of all, we must read the exam outline carefully, combined with the postgraduate test questions in the past three years, actually understand the topic, categories, and difficulty characteristics of this major mathematics examination, and perform the accurate positioning of review. Candidates should remember that the content that has nothing to do with the investigation will not be seen, so as not to waste time, they will not pay. Second, candidates should analyze, latency, and grasp the changes in adjustments and propositions of the outline. The outline is actually the scope of review of the Ministry of Education for candidates, and candidates should refer to the outline, fully review, and do not leave missions. This is the basic countermeasure of review. Master the basic methods of mathematics by reviewing the basic concepts and basic theories of mathematics compare the basic concepts of mathematics. To achieve good results in the postgraduate entrance exam, you must do "know each other". "Confisons" is first to understand their own advantages and weakness, thus being targeted in learning and review. "Knowing" is to study the characteristics and trends of recent propositions in recent years, so that the solution is found. This work is done by studying outlines and overhead tests. For example, the new knowledge point is generally the focus of propositions, and one of the characteristics of economic mathematics exams is 2-3 years of new knowledge points, so, in the review, it should be tightly combined with the outline and the true questions. "Know yourself". Through analysis of the outline, candidates have highlighted key points when reviewing, and also grasp the test hotspot. Generally speaking, the content required by the outline, the method of requesting the mastery is the focus of the exam, and the repeated content in the examination in recent years is the test hotspot. On the basis of system review of the concept, theorem, and formula, focus on key, difficulties, and hotspots, but don't specifically do bias, problems, weird questions, and formal exams basically no buds and weird. Before you start full review, you can seize key chapters and the constant test parts. Because comprehensive review is not equal to sharing energy and time on all knowledge points, but to grasp the key, difficult to get a comprehensive review Hotspots and major exam points. Many years of experience showed that important regular test sites in various subjects generally accounted for 60% - 70% of their examination outline.

Cut key test points can enhance the reintegration of review, speed up the progress of review and save a lot of time, improve the competitiveness of postgraduate and research, and make a solid foundation for the examination room. In terms of the characteristics of each class, higher mathematics is the top priority of postgraduate mathematics, and the points are large, and the contents of the need to review are also more. In addition, higher mathematics also have a comprehensive examination of cross-chapter and even interders, in recent years: a comprehensive question of level and integral; a comprehensive question of calculus and differential equations; a comprehensive question of seeking limit; spatial analysis geometry and multi-diversity Comprehensive questions for function differential; linear algebra and spatial analysis of geometric syndrome. This type of topic of the candidates can contact other mathematical courses to do well. The content of the linear algebra is translatted, the ring ring is buckled, and the knowledge points are deeply penetrated, so it is not only a number of inwarded angles, but also the solution method is flexible. It is necessary to practice a lot of practice under the premise of consolidating the basis. And in the 2002 outline, the test content of the linear algebra of mathematics is increased, and the difficulty is increased, and the ratio of linear algebra in the test paper is also improved, from the original total score to 15% to the present 20%, candidates have to increase the review of this part when reviewing. Probability Theory and Mathematical Statistics are some difficulties in postgraduate mathematics. In recent years, this part of the test rate is generally low. Unlike the calculus and linear algebra, probability theory and mathematical statistics do not emphasize solution methods, and rarely involve solving skills, and very emphasized in-depth understanding of basic concepts, theorem, and formulas. It turns out that the latest exam questions are very similar to the previous year, and most of these test questions have changed a statement, but almost the same thing. Therefore, for the candidates, one is to pay attention to the content you have been admired. For the previous year's examination questions, it should be digestive and consolidated; Second, pay attention to the contents of those years that have not been admitted for many years. In this way, through accurate positioning, grasp the focus and hotspots of the review, improve the efficiency and effect of review. three. Pay attention to the foundation, pay attention to and deepen review and understanding of basic concepts, basic theorems, and basic methods, candidates should pay attention to review for basic concepts, basic theorems and basic methods. Mathematics is a deduction, first of all, we must have an in-depth understanding of the concept (you must use your own language to describe), if you do, it is inevitable that you will answer if you ask, or even south. Second, it is necessary to keep theorem and formula, each of which is composed of basic definitions, theorem, and formulas, and their different combinations form different problems, and multi-level combinations form different complexity issues. So these definitions, theorem, and formulas are the foundation of the solution, and proficiency and deep understanding of these contents become the key to the success of the problem. It can be said that the agencies and formulas are equal to finding the breakthrough and entrance points of the understanding. The analysis of the mathematical answer sheet in recent years shows that an important reason for the loss of candidates is the basic concept, theorem is incomplete, the understanding is inaccurate, and the basic solution method is not good for proficiency, firm memory and understand all. Definition, theorem, formula, must first put all the formulas, theorem, definition, and then do a large number of exercises. If you have a basic problem, you can see your process, so that you really have the content that truly master the basic exercise. These questions look simple, but they can help us familiar with and master definition, theorem, formulas, so candidates can't see it because of these questions, don't pay attention to it. For a better than the side, if you look into a building, theorem, definition, formula, etc. is better than brick, and the basic exercise is a wall from the brick strip. It can be seen that the basic exercise is important for candidates. significance.

In addition, candidates should pay attention to the conditions, applications and deformations established by the theorem and formulas, and is flexible on the basis of understanding. In recent years, comprehensive test questions, more and more actual application questions, candidates should pay special attention. As the saying goes, "Boxing does not leave the hand, the song is not depressed" can achieve a subtle realm, and the learning mathematics is true, only the basic skills are solid, and there is a possibility of further improving the problem. For example, the most important basic skill in higher mathematics is limit, derivatives and points. The main basic work in the linear algebra is the primary transformation of the matrix, the method of solving the linear equation group, the matrix feature value, and the characteristic vector. The probability is mainly the case of the event probability, the distribution of two-dimensional random variables, the mathematical characteristics of random variables. Talking about these most basic masters, just talk about the solution methods and techniques, otherwise the so-called skill can only be a wooden, passive water. Talking about the foundation, some candidates may not be appreciated, think that this is far from the actual examination difficulty. Here, there is a problem that is difficult to test the problem. As long as you seriously analyze the test questions in the past years, it can be seen that the problem of difficult problems in the basic knowledge of the outline is deep, and the comprehensive application of basic concepts, basic theorems and basic methods. More flexible, there is no highly skillful buds, weird, 2002 test questions from the depth, the test is still reflected in the basic concept of studying mathematics, the basic theory, the basic method. As long as the basic concepts of candidates, the basic theory, the basic method is solid, it is not difficult to answer. Some intermediate-biased questions, which ended from extending the conversion on the basis of the basic concept. Only, in terms of understanding and application of basic concepts, basic theories, basic methods, emphasizing multi-point multi-angle. Candidates should recognize that although only the basic skills are not high, this is the foundation and premise of achieving good results. After a lot of candidates, the gap between the estimated points and the actual results of the candidates have become the basic skills. The score does not have a division, which directly affects "online". For candidates who are poor, pay more attention to the foundation, it is best to take the textbook to read it, keep in mind some important concepts, formulas and theorem, and combine the post-class exercises, digest these formulas, theorem The previously said that the definition, theorem and formula are the foundation of the basics. If the basic candidate, if you want to improve your own solution, you must work more. Basic training should be repeated. Learning mathematics, be sure to do a certain number of questions. Advocate refined, try to do some typical questions, do a variety of questions, a problem, to train your abstract thinking ability. The proven to some basic theorems, the derivation of basic formulas, and some basic exercises, to achieve "cooked energy". Consolidate the understanding of basic concepts, basic theorems and basic methods by basic training. "Higher hands is low" is a lot of candidates who are easy to commit to mathematics. Many candidates disdain for basic things. They think that these content is very simple, and they don't have to review them. If you have a candidate just "see", think you understand Just, rarely go to the question, and the result is a familiarity in the final exam, it is difficult to achieve good results. Therefore, in the review of mathematics, it must be down-to-earth, one step, a footprint, like a chess, to take the enemy old handsome, we must be old and actually defeated all the soldiers, steady, step by step, this kind can not change, Popularly occupied in the final test! The importance of the foundation has been self-evident, but only pays attention to the foundation, it is not. Too much attention to the foundation, it will be in the book, it is difficult to adapt to the examination questions. The purpose of making a good foundation is to improve. But too much increase, the foundation is not strong, causing the head to be light, and the force is not from the heart. Candidates must understand the dialectical relationship of the foundation and improvement, according to their own circumstances, the review progress, handle the relationship between the foundation and improve the ability.

In general, the foundation and improvement are interpolated and segmented, and at a period of one period is based on the foundation, the foundation is solid, and the improvement is improved. Then I entered another stage, and the solid foundation is also improved first, so repeatedly. Candidates are prone to such problems in this process, that is, I feel that I have already improved my basic review or for a period of time, and I even feel more and more, I have, I have encountered this situation, and the candidates should not be discouraged. Be convinced that you have your ability, as long as the review method is no problem, you should stick to it. Although there is no progress on the surface, the actual level is actually improving, because candidates have realized their own shortcomings in this period, in the adjustment and progress. At this time, it is the will of the candidates. The postgraduate will be a willpower competition, which not only needs rich knowledge and high ability, but also strong willpower. As long as you stick to it, you have a successful hope. Four. Strengthen the training of comprehensive solutions, familiar with the types and solving ideas of common examination questions, and strive to break through the idea of ​​solving the problem. The different points of the exercises on the postgraduate test questions and textbooks are in that the former is a comprehensive application on the basic concept, basic theorem, the basic method, and has a large flexibility, often a proposition to cover multiple contents, involved Concept, intuitive background, reasoning and calculation, etc. Therefore, it must strive to break through the solution idea. To make a large number of comprehensive exercises in the finished basis, and summarize more analysts, strive to have a common test type, characteristic, and thinking of a system Grasping. Many candidates are often difficult to adapt to the examination questions after completing the teaching book, and their highlights are not thinking, this is the breakthrough in the candidates should be solved. Candidates must master the solutions and techniques of all kinds of topics. Considering the characteristics of mathematics, the candidates are required to ponder all the rumors of all the solutions, which can usually participate in teachers with experience in teaching, or read the relevant counseling books. solve. In addition, when doing the questions, you don't have to write a complete solution step for each question. Similar questions generally see how to think, familiar with its arithmetic processes, so you can save time and improve the efficiency of doing questions. When choosing the exercise, candidates should pay attention to it. It is best not to do analog questions, and should do it once. Because the true error rate is relatively low, it is close to the actual test. Some simulations have an odds, and there is no performance. If you first do analog questions, if the choice of simulation is not good, it is a waste of time, and it also has a negative impact on his own solution. Through the true question, candidates can really understand the key points of postgraduate, difficult, and important is to master the topic of various common tests. After doing the true question, I will feel the quality improvement of my solving ideas, and there is also a new change in mathematical understanding. Many candidates have proven this in previous years. Candidates should pay attention to the intrinsic links between chapters while doing the questions, and the mathematical exams will have a comprehensive test and application test questions applied to multiple knowledge points. This type of test is generally flexible and difficult. Candidates should pay attention to the analysis of comprehensive typical examinations to improve their ability to solve comprehensive problems. Mathematics has its own rules, and an important feature of its performance is that there is very close relationship between each subject, and the links between each subject have to create conditions for comprehensive propositions, so candidates should conduct comprehensive test questions. And application questions training. Through this training, accumulate the problem of solving the problem, and connect all kinds of knowledge, transform the knowledge on the book into your own. Candidates have to do more examples when preparing for the exam, not just practice questions.

In accordance with the following methods, you must cover the answer before watching the first time, you must do it first; whether you have to make your own ideas in the blank place, especially if you can't do it. , Must record your true thinking method in the case, leave a future analysis, rather than the answer to the answer, so you can quickly find the feelings of the question. In short, when doing the topic, candidates have to develop a good question habit, be a "people", and seriously will have a good or unfamiliar idea of ​​good or unfamiliar words and their own thinking, usually looked at, Over time, your own solving ability will increase. For those questions with strong typical, flexible, inspiration, and comprehensive questions, special attention should be specially focused on the cultivation of solving ideas and techniques. The mathematics test is thousands of evolution, and its knowledge structure is basically the same. The subject matter is relatively fixed. There are often obvious solution routines. After skilled, it can improve the pertinence of the solution, and improve the speed and the correct rate. Of course, it is not enough to improve the mathematical ability. There have been a candidate, the usual solitary ability is very high, but the final test results are not very ideal. When you talk about your own failure, he said that he usually rely on the topic to improve the level, and lacking knowledge points At higher levels of grasp and application, the score rate is seriously reduced when there is a unfamiliar problem. Therefore, candidates can't do questions for doing questions. To consolidate the foundation, improve their grasp and use in higher levels of knowledge points. Be good at summarizing the summary, and the number of learning works can be best formed to form a familiar solitary system, which is to find corresponding solution ideas for all kinds of topics, thus facing a strange test in the final test. initiative. The problem of strengthening training before the test should pay attention to the problem. Strengthen the training before testing, and do a few sets of simulation test panels must be indispensable. Do a few sets of simulation test volumes within the specified time, you can understand what extent, you can understand your own weak links, and you can get rid of your weak link. Further experience gives the point to the test time through the usual training. There is a considerable number of candidates' experience proved that if candidates can extend through the issues to extend or integrate the test questions, they will use freed with us frequently, and achieve good results. According to the situation in previous years, many candidates often look much more and less. Some candidates complained too much after the test, can't finish or do something wrong. The reason is that it is the opportunity to lack the practice and no strengthening training before the test. Therefore, it is recommended that candidates do a few sets of simulation questions or sample questions in the limited time, then the answer to the answer to the answer. When doing simulation questions, pay attention to the following: 1. Pay attention to the assignment of the answer. It must be strictly qualified as a result as the practice. Time is only usually developed into a good habit. When the exam is available, there is also a number in your heart, and you will not be able to live in Zhang Huang. 2. Mathematical formulas must remember before doing questions, so they will have their hands when they use, 3. Lift it three, not just to do questions, pay attention to the connection between knowledge points. Let's talk about matters that should pay attention to during the answering process, that is, some experientials. The difficulty of postgraduate mathematics is getting bigger and bigger, but according to the previous year, there will be a basic question of 50 points. If you want to contact it, these 50 points must be caught. The top 4-5 questions in the test questions in the past 4-5 questions, almost all fills, and the choice is this. Therefore, when the candidate is arranged in the order of the answer, this is the simplest concept and calculation, and the score is easier. Of course, if there is a calculation question or certificate questions or the usual books or take the tutor. Examples can also do it first. Then answer the question. The answer is similar to the question simulation questions before answering the question, and then the answer has not been seen.

Last answer sheet, because of its comprehensiveness is too strong, and some single-choice questions are very conceptual, computational skills are also relatively high, so it is not easy to do immediately after completing the blank, so as to avoid self-confidence. Solving a single option generally has the following methods: Demonstration: It applies to the conditions given in the topic to analyze. Illustration: It is suitable for a function given in the question, such as parity, periodic, or events given by two events, which are particularly simple. Lift an alternative exclusion: Exclusion three, the fourth is the correct answer, this method is suitable for the fact that the function given in the question is an abstract function. Inverse Package: The so-called reverse push method is to assume some of the four answers in the four answers, and then do this alternative answer if the results are defiled. Assignment method: That is to say, an alternative answer will be brought to a specific number, if it is negative if it is contradictory with the hypothesis condition or well-known facts. Careful choice book. It must be emphasized that the counseling class or the counseling book is just a means of learning, and finally solving the problem. At present, some postgraduate counseling materials will be mixed together with the contents of mathematics (1) to mathematics (4). Even outline, candidates should pay attention to identification, the content of the admission is not required, do not have to be It costs a lot of valuable time and energy. The postgraduate reference book is an endless, how to choose the problem that each candidate will encounter. Some experts have mentioned the following suggestions to candidates: First of all, they should choose those of the induction and summary, in the method, the guidance of a specific method, and the guidance book with the specific method. This kind of counseling book is based on the topic, rather than engaging in sea tactics. Mathematics topics are like a sea, it is impossible to do it. The subject matter of mathematics is limited, and it is possible to master and understand their solution. Candidates should seize the subject in the review, it is best to back them. Second, there should be a forward-looking book. There should be methods and techniques that must be carefully explained in the book, which can be used to solve the test questions in the future research. Candidates don't have to choose too many books, but they must have important conceptual theorem and formulas in the selected counseling book, and have an analog summary. So how do you understand how many authors have these two characteristics? Candidates can learn from three ways. First, I have to go to the bookstore to talk more about the comparison; the other is to understand the situation in the graduate student reading; the third is to consult online, understand the information. When using the counseling book, candidates must understand that the review reference book is written for most people's needs. Specifically to everyone, the book is definitely unsuitable or wasting the time for him, so it must be The owner of the book is subject to the part of the book according to its own situation. As long as this can make a full use of limited energy. In addition, candidates should be inquiors when they are in the case. After doing it, I think about it, I think about it, and then look back at the prompt, catch the title. The use of the couch class is still necessary for the mathematics foundation for the use of a good tutor. First, you can use the professional advantages of tutorial and counseling experts and rich counseling experience to help candidates to grasp the examination points, key points, difficulties, and knowledge points; Second, they can "forced" candidates to conduct recurrent reviews. Improve the efficiency of review; third, it can provide accurate test information and precious internal information. According to the experience of candidates who have achieved good results in previous years, the exchange counseling class generally chooses spring class or summer vacation class, which is subject to personal ability.

If the individual's mathematical ability is strong, you can choose the summer vacation or directly select the sprint class; if the foundation is not good, the ability is better, it is best to report a spring class, because the spring class is relatively slow. , More detailed, mainly to help candidates play the foundation. At this time, I follow the counseling book, the effect will be better, and the classmates who have a poor self-learning ability can improve the efficiency of review. In the counseling class, it is best to take a look at the content you have to talk about each time before class, otherwise it is likely that the teacher's idea will affect the results of the class; try to take the teacher when prepared after class The solution step is completely understood, there is no relationship if you don't understand, note the mark, as the focus of future review. For self-made power, students who are very regular, can report summer vacation classes. Generally speaking, the summer vacation class is better than the spring class. After a few months of review, the candidates can read all the three parts of mathematics, so that they will not be difficult to be difficult by some of the uncommon concepts or formulas when they are in class, so they can think together with the teacher. After participating in the tutoring, the candidates should systematically review the basic knowledge of the exam must be completed on the basis of the skilled outline. This process should be completed before the couch. Then follow the class, follow the content of the teacher, and pay attention to the content of the teacher. After completing the secondary counseling, according to the various topic questions, conscious reading questions, on a certain number, further summarizing, solving the Issues. Some candidates may be more concerned about the choice of counseling work, because candidates who participate in the counseling class have associated their review plans and counseling classes, if the selected counseling class is not suitable for you or poor, it is likely to cause The failure of the entire review. Candidates have affected the final exam because of the problems of the counseling work. So how do you choose a tutoring class that is suitable for yourself? Experts recommend the candidates that when choosing a secondary class, you must first have a more accurate assessment of your ability, thereby choosing what type of class, such as a basic class or strengthening class. Second, candidates should consider from the teacher's strength, counseling materials, and school reputation and services of the tutorial schools. You can listen to the senior senior college entrance examination, because there is a personal experience, it is often able to provide more accurate information. Of course, if there are several classes, you can cooperate several people, one person reports one. This can save financial and energy, but also accept some knowledge and information. Candidates should understand that no matter whether they are tutors or counseling classes, they are just a tool for reviewing your review, which must not be superstitious with which of the books or which tutorial. Many candidates have proved that the good test results will eventually rely on their own brain, just listen to a few classes, and see a few books will not have a good effect. Mathematics exam is not just the knowledge of mathematics, but also the assessment of the comprehensive quality of candidates, such as psychological response capabilities, analyzing problems, ability to solve problems, and constrain the skills. There are many candidates to learn very well, the basic work is very solid, but I can't hold the "fighter" when the exam, so I don't have ideal achievements. There is also a classmate to test the "medical doctor", and the result is that the things that have been mastered have been blended. Therefore, it is very important for candidates a few days ago. The arrangement of the arrangement of these days will directly affect the exert of candidates in the examination room. Candidates should pay attention to the following aspects: one. Don't do analog questions or another one or two days before the test, because you will be easy to fight your self-confidence. At this time, you should do more basic normal test questions, think more about these questions of these topics, think more about the mistakes that you have made when you usually solve the problem.
